Non-in­ter­cep­tive Beam Po­si­tion Mon­i­tors pick­ups (BPMs) will be in­stalled along the beam­lines of the IFMIF/EVEDA lin­ear pro­to­type ac­cel­er­a­tor (LIPAC) to mea­sure the trans­verse beam po­si­tion in the vac­u­um cham­ber in order to cor­rect the dipo­lar and tilt er­rors. De­pend­ing on the lo­ca­tion, the BPMs re­sponse must be op­ti­mized for a beam of 175 MHz bunch rep­e­ti­tion, an en­er­gy range from 5 up to 9 MeV, a cur­rent be­tween 0.1 and 125 mA and con­tin­u­ous and pulse op­er­a­tion. The re­quire­ments from beam dy­nam­ics for the BPMs are quite strin­gent, aim­ing for the po­si­tion an ac­cu­ra­cy below 100 μm and a res­o­lu­tion below 10 μm, and for the phase an ac­cu­ra­cy below 2° and a res­o­lu­tion below 0.3°. To meet these spec­i­fi­ca­tions, the BPM elec­tron­ics sys­tem de­vel­oped by ESS-Bil­bao has been adapt­ed for its use with the BPMs of LIPAC. This elec­tron­ics sys­tem is di­vid­ed in an Ana­log Front-End unit, where the sig­nals are con­di­tioned and con­vert­ed to base­band, and a Dig­i­tal Unit to sam­ple them and cal­cu­late the po­si­tion and phase. The elec­tron­ics sys­tem has been test­ed at CIEMAT with a wire test bench and a pro­to­type BPM. In this con­tri­bu­tion, the tests per­formed will be fully de­scribed and the re­sults dis­cussed.

This work in­tro­duces a fast ac­qui­si­tion mul­ti­pur­pose con­troller (MC), based on a XML con­fig­u­ra­tion with EPICS in­te­gra­tion and Data Log­ging. The main hard­ware is an FPGA based board, con­nect­ed to a Host PC. This Host com­put­er acts as the local con­troller and im­ple­ments an IOC, in­te­grat­ing the de­vice into an EPICS net­work. Java has been used as the main pro­gram­ming lan­guage in order to make the de­vice fit the de­sired ap­pli­ca­tion. The whole pro­cess in­cludes the use of dif­fer­ent tech­nolo­gies: JNA to han­dle FPGA API, JavaIOC to in­te­grate EPICS and XML w3c DOM class­es to con­fig­ure each par­tic­u­lar ap­pli­ca­tion. Fur­ther­more, a MySQL database is used for data stor­age, to­geth­er with the de­ploy­ment of an EPICS ArchiveEngine in­stance, of­fer­ing the pos­si­bil­i­ty to record data from both, the ArchiveEngine and a specif­i­cal­ly de­signed Java li­brary. The de­vel­oped Java spe­cif­ic tools in­clude dif­fer­ent meth­ods: FPGA man­age­ment, cre­ation and use of EPICS serv­er, math­e­mat­i­cal data pro­cess­ing, Archive En­gine's MySQL database con­nec­tion and cre­ation/ini­tial­iza­tion of the ap­pli­ca­tion struc­ture by means of an XML file. This MC has been used to im­ple­ment a BPM and an LLRF ap­pli­ca­tions for ESS-Bil­bao.
